ABOUT ORGANIC HEAT TRANSFER FLUIDS
Typical areas of application
for organic heat-transfer fluids
Our organic heat-transfer fluids are used
in a broad array of applications
in several process areas.
The volume of heat-transfer medium essentially depends on
the specific heating or cooling requirements
in the relevant process and may
range from a few litres to several hundred cubic metres.
In processing plants in
the chemical and petrochemical industry
Depending upon the quantity of heat to be handled,
a volume of up to 400 m3 heat-transfer fluid
is frequently required and circulated in chemical processing.
| Alkylbenzene | Aniline |
| Aromatic separation | Caprolactam |
| Dimethyl terephthalate | Ethylene oxide |
| Formaldehyde | Isomerisation processes |
| Herbicides, insecticides | Paraffin sulphonate |
| Pharmaceutical active ingredients | Phthalic anhydride |
| Rubber and plastics additives | Terephthalic acid |
| Upgrading of coal |
In polycondensation
and polymerisation processes
Polycondensation exhibits a more moderate reaction sequence and,
depending on the plant size, can be adequately supplied with
heat-transfer media quantities of as little as about 10 to 40 m3.
Extremely fine temperature adjustments are required
to avoid discoloration and irreparable damage
to the polycondensate product.
| Mixed adducts | Polyacrylates |
| Polyamides | Polyesters |
| Polyethylene (LDPE) | Polymethacrylates |
| Polyphenylene oxide | Polypropylene (LDPP) |
Applications in plastics and rubber processing
High demands are placed on heat control
in the fields of plastics and rubber processing.
This market comprises an abundant range of the widest variety
of machines and appliances
with the relevant auxiliary units for energy supply.

Chemical reactions
A major application of heat-transfer fluids is their use
as heating or cooling agents in chemical reactions.
The following table lists some typical examples.
|
Supply of process heat and removal of process heat (cooling) |
Condensation reactions Cyclisation processes
Oxidative changes Cleavage reactions Hydrogenisation |
| Purification and separation processes | Distillation Fractionation Fractional crystallisation |
| Melting-on processes | Wire coating |
| Preheating of reactants |
Preheating air in oxidation processes Preheating products in thermal cleavage reactions |
| Energy recovery |
From waste gases in cleavage and combustion processes and in waste-gas purification |
Recently, energy conservation has become an area of interest.
This has led to an expansion in the fields
of application of heat-transfer fluids
with higher load capacities. As a result, the heat content
from waste gases out of blast heating apparatuses
can be fed back into the process via
a heat-transfer medium circuit
to preheat the fuels and fuel air.
Energy-saving designs in power plants, usually
in the flue gas dust collection system, function
in an analogous fashion via
recuperative heat-displacement systems.
In solar power stations the organic heat-transfer fluids
gained access to a completely new technology
at operating temperatures of 300 to 350°C.
